The mouse C3H 10TI/2 cell line was transformed to the malignant state using ionizing radiation. One of the transformed lines (R25) that was isolated, displayed some properties similar to malignant melanoma cells. The cells became dark and pigmented after prolonged time in culture and this cell line produced tumors in C3H mice. The radiation survival curve of R25 had a large shoulder which was also observed for human melanoma cell lines. R25 was more resistant to heating at 45.0°C than the normal cell line. Heating at 45.0°C before irradiation resulted in a reducion of the survival curve shoulder. The heat and radiation sensitivity of R25 did not appear to be related to the melanin content of these cells.
